Relax inducing device with heartbeat detection unit
First Claim
1. A relax inducing device comprising:
- heartbeat information detecting means for successively measuring a heartbeat attainment time, which is defined as a time period necessary to count a predetermined heartbeat number, said heartbeat attainment time being measured every cycle of the predetermined heartbeat number;
change-rate determining means for determining a change rate which is defined as a ratio of an initial heartbeat attainment time measured at an initial cycle of the predetermined heartbeat number by said heartbeat information detecting means to said heartbeat attainment time measured at a subsequent cycle thereof;
stimulus loading means for providing a stimulus to the user;
relax-level determining means for determining a relax level of the user by comparing said change rate with at least one predetermined relax-level threshold value; and
stimulus control means for controlling an amount of said stimulus according to said relax level determined by said relax-level determining means to induce the user into a relax state.

Abstract
A relax inducing device comprises a biological parameter detecting unit for detecting biological parameter of a user, stimulus loading unit for providing a stimulus to the user, relax-level determining unit for determining a relax level of the user by comparing the biological parameter provided from the biological parameter detecting unit with at least one relax-level threshold value, and a stimulus control unit for controlling an amount of the stimulus according to the relax level to induce the user into a relax state. In this device, since an optimum amount of stimulus is provided to the user on a real-time basis, it is possible to efficiently and smoothly induce the user into the relax state.

10. A relax inducing device comprising:
-
heartbeat-information detecting means for successively counting a heartbeat number every cycle of a predetermined time period; change-rate determining means for determining a change rate (Δ
HR) defined by the following equation;
space="preserve" listing-type="equation">Δ
HR=100X(HR(0)-HR(n))/HR(0),wherein "HR(0)" is an initial heartbeat number counted by said heartbeat information detecting means at an initial cycle of the predetermined time period, and "HR(n)" is a heartbeat number counted at a subsequent cycle "n"(=1,2,3 . . . ); stimulus loading means for providing a stimulus to the user; relax-level determining means for determining a relax level of the user by comparing said change rate provided from said change-rate determining means with at least one predetermined relax-level threshold value; and stimulus control means for controlling an amount of said stimulus according to said relax level provided from said relax-level determining means to induce the user into a relax state.
